Title: Improvements in or relating to the manufacture of cemented carbide discs
IPC: B22F3/14
Filed: 1931-09-07
Abstract: 386,359. Alloys ; tools ; electric furnaces. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. -(Assignees of Taylor, G. F. ; 115, Balltown Road, Niskayuna, New York, U.S.A.) Sept. 7, 1931, No. 25083. Convention date, Sept. 8, 1930. [Class 82 (i).] Thin cemented carbide discs for use as glass cutters, saws, &c., which consist of a sintered mixture of a carbide such as tungsten carbide and a binding medium such as iron, nickel, cobalt, &c., are made by placing a layer of the mixture of carbide and binder between two discs of carbonaceous material in an electrically nonconducting mould, heating the mixture momentarily to its sintering temperature, and simultaneously applying pressure, utilizing the apparatus and operating conditions described in Specification 385,629. The mould comprises a hard glass tube 18 in the ends of which are inserted plungers 19, 20 having central holes 21, 22 which accommodate a removable or temporary plug or rod 23. Graphite discs 24 having a central opening and layers 25 of the powdered material to be sintered are inserted alternately on the lower plunger. The plungers are positioned between extensions 8, 101 provided with adjustable sleeves 26, 27. A tube comprising the carbide, binding metal, and starch paste may be squirted, and after removing the paste by firing in hydrogen equal lengths may be cut and separated with paper to form the layers 25. The carbide discs may also be reinforced by the introduction into the powdered material, prior to heating and pressing, of small molybdenum wires, for example C- or O-shaped wires. Diamond dust may be added to the powdered materials as described in Specification 349,732, [Group XXIII], the discs preferably being also reinforced by wires. Carbide discs with no central aperture can be produced by omitting the plug 23 and employing solid plungers and solid graphite discs 24. Specifications 213,524, 288,521, 289,477, [all in Class 82 (i), Metals, Extracting &c.], and 351,189, [Group XXIII], also are referred to.

Title: Apparatus for playing a table game
IPC: G07F17/38
Filed: 1935-09-10
Abstract: 462,546. Table game apparatus. SHYVERS, K. C. Sept. 10, 1935, No. 25168. [Class 132 (ii)] [Also in Group XVIII] Game apparatus in which a ball, or other object, 11 is propelled by the player over a playing surface 10 and is arrested at a predetermined point (opening 46) on said surface, is characterized by a second movable member (15, 32) and means (arm 101 and contacts 102, 104) disposed on the playing surface in the path of the ball, or other object, to effect stoppage of the second movable member. In the position of rest of the machine the ball 11 in opening 46 holds an arm 101, Fig, 12, against spring 103, so that contacts 102, 104 in the circuit of motor 25, are held open. This motor through gearing, drives a hand 15, Fig. 1, over a scale 14, this hand having rigid with it, under the playing surface 10, a contact arm 32 which wipes over twelve studs 28 which correspond to the twelve numerals of scale 14 and are wired to twelve lamps 41 situated around a scoring scale 42. If any of three coin slides 55, 56, 57 (for nickels, pennies, and dimes) is pushed inwards the slide rocks an arm 48 rigid with a shaft 49 so that an arm 47 rigid with this shaft raises the ball, which thereupon rolls down to plunger 45 and allows contacts 102, 104 to close so that the motor drives the contact arm 32. When ball 11 is propelled up path 43 by plunger 45 it returns to opening 46, separates contacts 102, 104, and stops the motor 25. If at this moment, the arm 32 rests on a stud 28, the corresponding lamp 41 is lit to indicate the score. Each coin slide is wired to a lamp 59, 60, or 61 so that it may be seen which slide has been pushed in. An indicator needle 150 is coupled to the spring-controlled plunger 45 so that the force of propulsion may be varied at will. Time check. After the device is released by a coin slide, a limited time, e.g. one to one and a half minutes, is allowed. When a coin slide is pushed in, a shoulder 90 on it, Fig. 2, rocks a bell crank 69 so that a depending arm 71 on the latter rocks an arm 72 pivoted to a disc 73, the arm resting against a stop 75 so that disc 73 rotates clockwise, Fig. 12. A pin 83 on a lever 84 pivoted at 85 is thus forced out of a notch 88 on disc 73 so that by its consequent counterclockwise rotation lever 84, through its pin 89, allows contacts 91, 92, 93, 94 in the main circuit to close. The rotation of disc 73 winds up a spring, the latter with an escapement returning the disc 73 counterclockwise, Fig. 2, until the notch 88 once more registers with pin 83 and opens the main circuit. Fraud, preventing. Normally a ball 136, Fig. 8, rests upon a plunger 133 and holds the latter depressed so that contacts 139, 138 are open. If the whole apparatus is tilted the ball rolls off the plunger, which rises and allows contacts 138, 139 to close ; these contacts completing the circuit of lamp 141, Figs. 12 and 1.
